Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken breast
- Provides the main protein and bulk of the casserole filling.
- Low-fat mayonnaise
- Adds moisture and creaminess so the filling binds and stays tender.
- Reduced-fat sour cream
- Adds tang and creaminess, keeping the filling moist during baking.
- Swiss cheese
- Melts into the filling and browns on top, adding richness and flavor.
- Baked potato chips
- Form a crisp, golden topping that contrasts with the soft filling.
- Water chestnuts
- Add a crunchy texture that stays firm after baking.
The step that matters
Bake until the filling is bubbly and the chips are golden. The filling must heat through and the cheese must melt, but the chips can burn quickly at 400°F. Watch the topping closely so the filling is hot and the chips are golden, not dark.

Fit is the average pairing score against chicken, onion, pepper, parsley, cream, lemon, mustard. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
